Open Source Assembly Assemblers

The "Open On-Chip Debugger" provides JTAG/SWD access from GDB (or directly with TCL scripts) to processors with ARM and MIPS based cores. See website for full list of supported targets.

A disassembler for the linux platform. Currently this supports x86 ELF files assumed to be written in C and output to intel- syntax assembly language; however the design is modular and replacements for any of these can be written.

Mecrisp - A family of optimising native code Forth implementations for MSP430, ARM Cortex M, RISC-V RV32IM(C), MIPS M4K and FPGAs.

Udis86 is an easy-to-use minimalistic disassembler library for the x86 and x86-64 instruction set architectures. The primary intent of the design and development of udis86 is to aid software development projects that entail binary code analysis.

JWasm is a Masm-compatible assembler. It supports 16-, 32- and 64-bit code, instructions up to AVX and various output formats. It's written in C.

Z88DK is a complete Z80 / Z180 development kit that includes C compiler, assembler, linker, a tool for generating executables in a number of formats, and miscellaneous other tools. Over 80 machines are directly supported out of the box including standalone Z80 and Z180 embedded systems. Z88DK's extensive assembly language libraries give it significant performance advantages over other Z80 C Compilers. Building software for standalone or generic Z80 systems: https://www.z88dk.org/wiki/doku.php?id=libnew:target_embedded Visit us at github for the current version with bugfixes and new features: https://github.com/z88dk/z88dk

The NASMX Project is a collection of macros, includes and examples, which are meant to help NASM programmers develop 32-bit and 64-bit BSD, Linux, Windows, and XBOX software in a fraction of the time it normally takes.

Simple 8085 assembler and disassembler for educational use. The 8085asm generates the map file and intel hex file. It support the directives EQU, ORG, DB, DS and END.

A simple absolute mode assembler for 6800/6801. Handles the complete published set of opcodes/mnemonics. Mostly source-language compatible with the common assemblers in use circa 1985, but no macros. Now uses standard LDAA syntax by default. Produces basic S1/S9 object files and assembly listings, and now binary and MC-10 compatible cassette images. (This is for the 8-bit 6800, not the 16/32 bit 68000/coldfire processors.)

A small simulation of an experimental customized Cpu called FlexxCpu. A virtual Cpu whose assembly instructions have been strongly influenced by old cpus architecture (8080, 6809, z80, 68k, etc...)

The M6811 Code-Seeking Disassembler is a command-line tool that lets you enter known starting vectors for a given code image for the 6811 micro. It will disassemble the code and follow through branches to assist in the separation of code and data. Its companion Fuzzy Function Analyzer uses DNA Sequence Alignment Algorithms to locate similar code in multiple binaries, facilitating reverse-engineering. Originally written to analyze code from GM automotive engine controllers, but is useful anywhere a 6811 micro is being used. Version 1.0 was written in Borland Pascal in April 1996, and updated to v1.2 in June 1999. It was later rewritten to C++ in July 1999 through Jan 2000. While it's been freely available since its creation, it's being released here as an open-source project so the world can better use it as it sees fit. Version 2.0 is completely reworked in 2014 to compile and run with GCC and STL to make it fully portable and accessible to all computer platforms.

This is a windows version of my Linux disassembler. It is an old version, no where as good as the Linux version.

This package is a set of includes that extend flat assembler abilities in producing various file formats & executables for various environments. Main target is provide winSDK like set of includes to produce executables for win32/win64 environments and a numerous demos for that. additional targets is to provide support for various rest environments & file formats within one package. Within that includes are present ones for support NE-executables targeted to win16 with demos, ones for support KEX-executables targeted to kolibryOS with demos, ones for producing ELF formats, ones to support BMP format, ones to support DB format (DB format is text file that could be assembled to binary by any assembler )

Simple ide and assembler for z80 possessor.

1664 macro assembler, simulator, console debugger, interpreter (host system calls.)

AsmDis - disassembler for x86 Linux ELF executables. AsmDis is a interactive disassembler that allows code and data to be identified. Optionally the output can be used by AsmSrc to generate source files.

AsmTrace traces ELF executables, showing registers and disassembly. Triggers can enable and disable tracing.

Calcsys is a system tool for the TI-73, TI-83 Plus, and TI-84 Plus calculators. It provides developers with: Hex Editor, Disassembler, I/O Port Monitor, System Flag Editor, Console, VAT Viewer/Editor, and more.

This is a student project designed to compete in the 2010 IEEE Computer Society Student Competition: http://www.computer.org/portal/web/competition/2010competition The Code Red architecture is designed for extremely lower power environments, like distributed sensor networks. Included is a design of that architecture, a Java-based simulator, an implementation (without vector instructions) designed as a Logisim circuit (http://ozark.hendrix.edu/~burch/logisim/), and more. The name "Code Red" comes from our team name, the Red Team. Since the competition dictated a small team size, our professor split the class and gave each group a color. We liked the name "Code Red" and chose it to represent our team and school's color (UMass' official color is Maroon.) Only later did we realize that "Code Red" was the name of an unrelated computer worm from 2001.

The ebe programming environment is a nice IDE designed for developing Assembly programs. It also handles C and C++ programs as well since there was not much extra effort. It used to support Fortran and this could return if people want Fortran. This project is an effort to recode ebe using C++ and QT. Originally ebe was coded using Python, Tkinter and Pmw, which worked out pretty well. The QT environment offers substantially better GUI controls. The most obvious difference is that Python ebe has a lot of separate windows, while the QT ebe will use 1 main window and a collection of dockable subwindows. This will make it easier to use.

Object Oriented Progamming for Assembly Language - Javalin enables the assembly language programmer to define and create portable object packages using the Javalin object oriented programming model.
